Kremlin media fake: Poland openly recruits its residents to join Ukrainian tank crews

“Zostań Żołnierzem Rzeczypospolitej” is a campaign advocating enlistment for contract service in the Polish army, which has nothing to do with recruiting volunteers for foreign formations. A poster with an image of a tank and a call to “defend the native Polish lands” in Ukraine simply doesn’t exist.
In Simonov's video, a promotional poster for Tess Gerritsen's book “The Secret I Will Not Reveal” (”Sekret, którego nie zdradzę”) can be seen next to the next to the poster allegedly calling to “defend Poland in Ukraine.”
